You mentioned audio is copied which I assume means no reencoding. So if its dts it will be larger then ac3. At least on your dts dvds you can use the ac3 track to save a little space. Last edited by yoda; 6th Apr at Donatello - The Shredder?

Whichever encoder GUI you use, a CRF value of 18 when using the x encoder default encoder settings is considered to be basically "transparent".
The higher the CRF value, the lower the quality and the smaller the file size. How large the final file size will be depends on how you resize the DVD before encoding and how hard it is to compress. On average, using a CRF value of 18 and copying the original AC3 audio, the final file sizes generally average somewhere between 1. That's just a rough average though If the average file sizes are still too large for you using a CRF value of 18, anything up to around CRF 23 should still look pretty good.
And if the video is particularly noisy, running a noise filter over it while encoding will make it easier to compress and reduce the file size. PS You shouldn't be using a constant bitrate either. CRF mode uses a variable bitrate in order to distribute more bits where they're needed and less where they're not to give you a higher visual quality for a given bitrate.
If you want to select a bitrate when encoding, you should be using the 2 pass encoding mode I don't know if Xmedia Recode has a 2 pass mode , which still lets you choose the average bitrate, but uses variable bitrate encoding as the CRF method does. CRF lets you select the quality but the file size will be unknown. Instead of starting a new thread I'll just ask my next question here.
The last DVD I rencoded had a res of x after cropping out the black bars. If that flag is still embedded in my output file, the picture would be displayed at x but this would be incorrect because of the cropping I did. If the flag is not kept, then the resolution is displayed at x which is also incorrect. However, everything I've played the output file on has displayed it properly and I cant figure out how.
Thanks for the help. The aspect ratio can be expressed as either the shape of individual pixels or the shape of the entire frame.

In conclusion, the best settings to rip DV with the best quality, speed, and size: H.
It requires clicks only to rip DVD without complicated settings. Even novice users can do it fast and easily. Run the software and insert the DVD into the computer. Then click the Disc button to load the DVD info. It will automatically remove any protections and detect the right title of any old or new DVDs.
Then the software will bring you to the output format window. When selecting a preset consider parameters such as the picture quality, encoding speed, and output file size. Select MP4 H. Next to the MP4 video profile, enable the encoding to HQ to get better video quality. If you really want to improve speed and sacrifice quality, go for the LQ encoding. Back to the main interface, click the gear button next to the selected profile.
Here you can change various DVD ripping settings like resolution, bit rate, codec, aspect ratio, audio ratio, etc. Leave other parameters like frame rate, aspect ratio, sample rate, etc. Enable the Hardware Accelerator and it can run at an avg. You need to download and launch Leawo Prof. Media in your computer. It will take a few seconds to load the video. Choose a mode and click "OK" button. Step 2.
Next, we need to choose output profile. There is a drop-down box named "MP4 Video" by default. Click the box and hit "Change" to enter the "Profile" panel. Select the one that fit your need well. Step 3. Then you could enter the Profile Settings panel by clicking the same drop-down box and then clicking "Edit" option. Step 4. After profile settings, navigate to the "Convert" interface, on which you need to click the green "Convert" button to set output directory for saving the output files.
Step 5. Then you can start the final conversion process by clicking the "Convert" button at the bottom of sidebar. In all, boosted by advanced accelerating technology and world-leading disc decryption technique, Leawo DVD Ripper is as fast as lightning in ripping and converting DVD. Why not downing and having a try by yourself!
So many video file formats, so many handheld video players, so many online video sites. To have your favorite clips how you want them—whether that's on your DVR, iPod, PSP or desktop—you need the right utility to convert them into the format that could satisfy your need. What's your favorite way to convert video to the right format? In fact, there are many different DVD encoding programs on the market.
